GreenPlanet Nutrients Karbo Boost is a powdered supplement and carbohydrate additive for the flowering stage, designed to feed microbial life in the root zone and support bloom performance. It’s a dry fertilizer additive nutrient made for growers who want focused carbohydrate support without turning their routine into a long list of extras.
Karbo Boost is positioned as microbe food that supplies a vital source of food for microbial life. By delivering an added source of carbohydrates, it’s intended to encourage the rapid expansion of beneficial microbe colonies in the grow medium. That root-zone support matters most in the flowering stage, when plants are pushing hard and the garden benefits from a more active rhizosphere.
GreenPlanet describes carbohydrates as a clean source of energy that supports heavy fruiting and helps keep bloom development moving forward. With healthy microbial life in the rhizosphere, Karbo Boost is intended to support nutrient uptake by helping microbes break down larger elements into simpler chemical components that are easier for the plant to uptake and absorb. The same active root-zone biology is also described as helping mobilize nutrients while supporting water and oxygen absorption in the root zone, which supports faster and stronger growth during bloom.
The facts layer is simple and specific. Karbo Boost is described as a formula built around naturally occurring carbohydrates, and it is listed as 100% dextrose as the non-plant food ingredient, clearly positioning it as straightforward microbe food rather than a complex blend. This keeps the product identity clean: a carbohydrate additive focused on feeding beneficial microbes, supporting bloom energy demands, and helping the plant make better use of available nutrition.
Karbo Boost is stated as suitable for outdoors, hydroponics, drain-to-waste, recirculating systems, and soil/soilless gardens, making it easy to fit into a wide range of setups without changing the product’s purpose. This is a good fit for growers who want a flowering stage carbohydrate additive that supports beneficial microbe colonies in the root zone and helps promote a healthy, aromatic crop with bloom-focused performance.
Step-by-step mixing and feeding instructions for Green Planet Nutrients Karbo Boost - 600 Gram.
Fill your reservoir or watering container with clean, room-temperature water first. Shake the bottle of Green Planet Nutrients Karbo Boost - 600 Gram well before every use. Using the feeding schedule below, measure the recommended dose and add it directly to the water while stirring. Allow the solution to mix fully before adding any other fertilizers, additives, or supplements.
Always add nutrients to water — not the other way around. Mix thoroughly between products to ensure an even, stable nutrient solution.

Dextrose can support plant growth by quickly feeding beneficial root-zone microbes, which can improve nutrient cycling and root activity, and it’s unique because it provides fast, simple energy compared to slower, more complex carbohydrate sources that don’t trigger such an immediate biological response.
